For notes in the layouts I use a text object that I destroy on layout start...

I would love to see a method of deforming sprites - but in conjunction with the inclusion of an integrated bones animation system with object nodes hierarchy and a timeline editor for animations (see Godot engine). I digress....

^ That sounds nice to have.For notes I personally create a blank sheet, put a comment in there and write down TODOs, bugs, variable states, etc. Using Shift+Enter to make it multi-line, it works perfectly.
